Description

Precision SFZ Flank Locking Nut Features

The SFZ Flank Locking Nut utilizes internal setscrews that intersect at a precise 30° angle. Consequently, this design drives the locking brass pins to stick perfectly against the shaft thread flank, providing maximum locking security without thread deformation.

Furthermore, this advanced locking mechanism eliminates traditional mechanical fasteners and simplifies overall machine assembly:

  • Eliminates the requirement for thrust washers or keyways.
  • Simplifies assembly and disassembly procedures during maintenance.
  • Allows repeated re-use when operators handle the component properly.
